Heavy-weight floor impact sources should have the characteristic of being generated in everyday life by children jumping and running. It is therefore necessary to enable measurement and evaluation sufficiently for the dynamic performance of floor structures with regard to this form of actual impact source. On impulsive force characteristics, the impact frequency of impact sources is especially important, and in order to efficiently reflect the effects of peripheral constraints caused by beams to the measurement result of a floor slab vibration in a manner which corresponds to the actual impact source, it is necessary to maintain the impact time of the impact source to approximately 20 ms or more.

The natural bank of the Shokoji River in Sado was changed into concrete structure in 1978 except the upper part of the Temple. Interviews with citizens have made clear that there are 68 points of immediate contact with the river. The authors classified them into 7 categories: controlling flood, daily house work, farming, playing, festival, ecology, and waterscape. These contacts were made possible by the make of the river bank. Citizens' responses are concrete and present important sources for application in a small river in a town.

Recently, in order to resolve bio-function and to make diagnosis, it becomes popular to measure weak magnetic fields from brain by using SQUID (Superconducting Quantum Interference Device) magnetometer with extremely higher sensitivity. For the fundamental study of the brain, a new 19-channel SQUID magnetometer system, which would be easy to operate and less expensive than the commercial base systems consisting of multi-channel SQUID sensors with the first order gradiometers and a magnetically shielded room with higher shielding factor of over 1000, has been developed. The total hardware system consists of 19 sensors with the second order gradiometers, readout elecronics, a liquid helium dewar, a gantry and a prefabricated magnetically shielded room (PMSR). By using PMSR with moderate shielding factor of around 20 and the second order gradiometers, magnetic noise which is low enough for measuring brain fields can be achieved. In this paper, first, design concepts of PMSR and a gantry developed as a peripheral equipment of this system are explained. Second, the magnetic shielding effect, electromagnetic shielding effect and evaluation on the magnetic noise due to vibration of the shielded room and gantry are discussed.

Nation wide inquiry was carried out in order to obtain public opinion and the actual state concerning house lighting. The results are shown as follows. 1) There were two types of rooms, a single purpose one and a multipurpose one. 2) Although people have, to a certain, a pre concept of what suitable lighting for the situation should be, many of them chose stereotyped methods such as ceiling light, and did not change the lighting method for different situations. 3) As for the respondents' personal preferences, yearly income was related to the number and types of lighting equipment. 4) Despite satisfaction with the present state, many people desired that the interior lighting be comfortable. 5) Awareness for energy conservation was relatively high.

Design approach of air-conditioning system is described for a large indoor stadium project. Displacement ventilation using task air supply system is adopted to minimize air conditioning space which is expected to contribute energy savings. Dack surface of the fixed seats is used to control air distribution around spectators. Exhaust air is sucked from the roof vent where wind help to make negative pressure by airfoil effect. Full-sized model is used to decide the optimum shape of the seats, and to confirm human comfort conditions of the system. In this paper, we report the study process and results of the experiments.

This paper reports our study on the most desirable operation modes of air-conditioning system. The Kansai International Airport Passenger Terminal Building (PTB) is a gigantic structure of 290,000 m total floor area served by 305 air-conditioning systems in total. We prospected an enormous energy demand, but from our simulation analysis, we could find that maintaining the energy conservation and service level required can coexist if air-conditioning operation mode is carefully selected on each PTB operation. In order to accomplish this, however, a new most desirable operation controlling system will be needed, so we studied its prospective fundamental organization and functions.

This report presents a summary of the architecutural manual books that were written before the early part of the 17th century. Those old records were handed down to the recent years by the KOBAYASHIS who were inaugurated as the DAIKUTORYO that was the post for the authorized carpenters in SYONAI-HAN. Their descriptions were about the architectural techniques to all kinds of architectures and the architectural formalities, so they were important to study Japanese Middle Ages architectures. Among those architectural techniques, this report presents especially the systems of TOKYO as the one of the important parts of the Japanese traditional architectures.
